Principles of Reverse Osmosis
How Fresh Water is Produced
Reverse Osmosis or is a process used to remove large volume of contaminants from
water by forcing the fluid through a semi-permeable membrane.
Osmosis
Osmosis is a naturally occurring process where a weak solution will cross a semipermeable
membrane to mix with a highly concentrated solution. For example, a freshwater solution will
naturally want to mix with a saltwater solution.
Reverse Osmosis
To reverse this process work is put into the system using a pump. The pump causes pressure
to build up on the saltwater side of the membrane. This pressure forces water across the
semi- permeable membrane. The membrane is designed to allow the water molecules to
pass while preventing the salt and other solids from doing so. Fresh water is collected on the
other side of the membrane as a result.

System Requirements and Operation Guidelines
Plumbing
The membranes and Freshwater RO flow of water with
a maximum temperature not to exceed 113°F. Please see Complete Install Guide and the One-Line Flow
Drawing on page 13 for proper plumbing of the system.
Tube Cutting and Installation Procedure for Quick Connect Fittings
Cut the tube square and remove burrs and sharp edges.
Ensure the outside diameter is free of score marks. For
soft or thin-walled tube, we recommend the use of a
tube insert.
Push the tube into the fitting, to the tube stop.
To disconnect, ensure the system is
depressurized, push the collet
square against the fitting. With the
collet held in this position the tube
can be removed.
CAUTION
ANY RESTRICTIONS OR BLOCKAGE IN THE CONCENTRATE LINE CAN CAUSE BACKPRESSURE, WHICH
WILL INCREASE THE OPERATING PRESSURE. THIS CAN RESULT IN DAMAGE TO THE
COMPONENTS.
